Heat the oil in a large pot over medium heat. Crumble in the sausage and cook until browned, 5 to 7 minutes. Add the squash, zucchini, eggplant and onion, and cook until softened, another 5 to 7 minutes. Add the mushrooms and okra and cook 5 minutes more. Add the garlic, jalapeno, crushed tomatoes, chicken broth, white wine, red wine vinegar, oregano, basil, sugar and some salt and pepper; stir to combine. Cover and cook for 30 to 35 minutes, stirring every now and then. When done, place in bowls and top with the Parmesan. Enjoy!!
